; My invention relates to demountable office partitions and moreparticularly to a floor 1 to supplement the ceiling lock, described inmy former application, in holding'a parti tion, of the characterdescribed, secure ly in place.

A further object is to provide a demojunt able partition whichreadily'may be erected in an oflice, or a room of any-kind, without theuse ofnails or fastening screws and may be secured to ceiling and floorso as to be as rigid as a permanent partition. 1 7

A further object is to provide a floor lock device which may be employedfor-fastening oflice railings, sectional counters, etc. as well, aspartitions, to floors. 1 I

Other objects and advantages will appear hereinafter and while I showherewith and will describe a preferred form offconstruc tion'l desire itto-be understood that I do not coniine'my invention to suchpreferredform.

but that various changes and adaptationsmay 6 be made thereinwithout"departingfrom the spirit of my invention as hereinafter claimed.Referring to the drawings which accom: pany this specification and} forma part there-1 Fig. 1,is a view in elevation of a typical partition inwhich my ceiling lock andfloor lock are used as fastening means.

- -While the partition shown in these draw ings will be seen to be ofthe same general construction as that sh own in my former .a plication,a .somewhat fuller description .of certain details thereof will be givenhere, in order to facilitate a clear understanding of the variousrpartsand their relation to each other: The reference numerals here used todesignate the various parts do not, therefore, coincide with those-usedto designate similar parts in the former application;

-:-A slightmodification in theconstruction of the. partition, because ofthe added floor lock feature, is the provision of a foundation strip 10,with a longitudinal groove 11 in its upper face adapted to receive'thelower ends of. the partition sections .12. =Each of saidsection'siszmade in the form ofa unit resembling a door-,1 with a top rail 18, amiddlerail 14', and

a bottom rail 15 fitted between two'stiles' 16 and held in spacedrelation to ea'ch-other by. thenna panel 17 and a glass platelS beingfixed in tlie'lower'and upperfparts, respec-f tively, of each section.The box-cornice 19,

is mounted on theupper ends of sec tions 12 is equipped with a copingstrip. 20 havinga longitudinalgroove 21- in its, upper transom sections22. Pilas'ters are formed by longer casing pieces 23 fixed betweenfounda tion'strip10 and cornice;l9 so as to :cover the, joints betweenadjacent partition sections, andshorter casing pieces 25L fixed betweencoping strip 20 andcap members 25 (design nated '23 and fully described,-in, my former application) so as to cover the oints between adjacenttransom sections.

My floor lock comprises an expansion shield 26 of any suitable type, arelatively longrodbolt 27, with a removable head 28 on its upper end anda'screw threaded lower end 29 adapted to screw into the upper end orbolt-head 30 of the expansion shield, and a series of clownturnedhooksor anchors 31 mounted on said rod-'27 in spacedrelationtoeachother, said anchors beingprovided with bearings 32 in which therod may turn freely. WVashers 33 are placedcon the rod above and belowthe anchor bearings and pins 34 are fixed in the rod so as to hold saidwashers in contact with the bearings and thus to retain the anchors intheir proper positions. A clamping plate 35 inthe form of an elongatedwasher, isinserted under the head-30' of the" expansion shield bolt. 7 V7 One-"of the'fioor locks thus-formed is placed between each adjacentpair of partition'sec- V tions, longitudinal grooves 36 being runintheir stile edges to provide clearance for'rod' 27 and notches 37 beingcut therein at suitable intervals toprovide clearance for anchors 31'.The" rod and anchors are attached to the edge of one of the sections bymeans of suitable staples 38 driven therein.

The corners of partition sections12 are cut away as at 39 to provideclearance for clamping plate 35 and bolt-headv-30, of the expansionshield, and the corners of transom sections 22 are cut away as at 40 toprovide-clearancefor bolt-* head 28.

Catch plates 41 are fixed at spaced inter vals, corresponding to thespacing of anchors- 31, on the rear faces of pilaster casing pieces 23*,suitable recesses 42 being cut in said rear faces, under catch-plates41, to permit the" anchor hooks3'1 to pass behind them.- Long'itudinalgrooves 44'are also" cut in the rear face'of vcasing pieces 23,:adjacent the edges thereof, said grooves being adapted to receivetongues 45which are fixed in the faces of stiles 16' ofthepartitionsections, the purpose of these'tonguean'd grooves being to prevent anyside/wise shif-ting'of the pilaster. casing with reference to the joints" between the par ti-tion sections. 7, I

In the process of erecting a partition ofthe type, here shown holes46,spaced to correspondto the width'of the sections 12 and of a siz'e toreceive expansion shields 26, are

' bored through foundation strip 10"and coinaiding holes 47 are drilledt a prop ndepth infthe floor 43'. Foundation strip 10' is then ai -in PQi iQ n t floor and expansi shields 26 are inserted through holes 46 intoholes 47, with clamping plates st lying dn greets-11"; and theif-bolts30 are screwed;

Partitionsections 12" are then' set up and threaded ends 29' of rodboltsa? areserewedintothe bolt hear-Is 30' of expansion shields 26, far enough tojust hold them upright. Heads 28 are now removed from rod-bolts 27 andbox-cornice 19, which has been provided with holes 49 to receiverod-bolts 27, is mounted on the upper ends of sections 12, heads 28 thenbeing replaced on rod-bolts 27 with washers 50 under them. Pilastercasing pieces 23 are now set in place on opposite sidesof the partitionsections and Mabel-n27 arescrewed down into expansion shields 26" untilanchor hooks 3-1 engage catch plates 41 so as to hold the casing piecesfirmlyc'lain'ped against the partition sections.

with tongues 45 inserted in grooves 44.

Transom sections 22 are finally set in groove 21 and secured in place toceiling strip 51 by means ofmy ceiling lock'52, pilaster casing pieces24 and cap' members 25 being set in place and fastened as described inmy former application.

It will be seen that a partition may be constructed in the mannerdescribed without nails or fastening screwsso that it will be as rigidand durable as apermanent partition,- whilebeing in a condition to beeasily removed at anytime. After removal the only trace" l'eft'behin'dis a few. holes in the floor which readily may be filled up so as to becompletely eflaceda Having'thus illustrated and described my invention,I claim:

1. In a demountable'partitionmade'in sections, a foundation stri havinga longitudinal groove adapted to receive the lower ends of the partitionsections;- clam-ping means in said foundation strip'adapted tosecure itto afloor; a cornice copingfresting on the upper ends'of thepartitionsections and loclnng means extending downwardly from saidcornice coping to said clamping.
